Add Toast Notification on warnings or errors.

[kriserickson]

I found that some errors and warnings sent to the logger where getting ignored so I added a visible notification of errors and warnings sent from the server.

Toast notification looks like good idea, but it's very rude to upgrade whole script to your own code style

@syabro it looks like some of the code was actually from 11 months ago. I think I updated some of the code formatting since then 😄

I do agree those should be updated. I haven't had time to play around with this PR yet, but hopefully will get to soon.

Apologies if any of the code formatting changed, I tried to change as little as possible however I use WebStorm which auto-formats code on paste's and such and @ccampbell is correct the changes were actually made from the codebase from months ago and I obviously had some merge issues when I merged to the latest code (which is much cleaner BTW).

To others looking for a solution, this extension should do it for every console error:
